Physical inactivity is an important public health concern. Strong evidence exists linking insufficient physical activity (PA) with an increased risk of many adverse health conditions, including major non-communicable diseases such as coronary heart disease, type 2 diabetes, and breast and colon cancers—all of which can drastically reduce one’s life expectancy. The media holds great potential to encourage positive health behaviors among the broader community. However, evidence to support traditional mass media campaign approaches to PA promotion remains inconclusive, with most televisionbased campaigns falling short of achieving the PA changes they were designed to promote. Researching alternative methods of delivering PA messages could improve the efficacy of television-based health promotion efforts. Reality television presents one such alternative. This dissertation consists of a systematic literature and two separate, but related, studies. The first study examined the associations between individual characteristics, health-related behaviors, impressions of a PA-themed reality television show concept, and intentions to engage in active transportation (AT) using a randomized two-group (independent) post-test pre-experimental design. Results showed that age, race, and education were significantly associated with impressions. Mild and moderate intensity exercise was significantly associated with behavioral intentions, while impressions of the show explained 19% of the variance in behavioral intentions. There was a statistically significant difference between TV show conditions with those exposed to the AT concept reporting higher AT behavioral intentions. The second study assessed the show concept in formative research and—in addition—examined the associations between individual characteristics, health-related behaviors, impressions of a PA-themed reality television show concept, and intentions to engage in active transportation (AT) using a non-randomized two-group (independent) post-test pre-experimental design as well as in-person, semi-structured interviews. Those exposed to the AT show concept showed higher behavioral intentions for AT, and there was a significant positive correlation between impressions and behavioral intentions in the AT show group. Semi-structured interview data indicated that a majority of research participants had positive impressions toward the PA-themed reality show concept and the show’s characters. However, the visual and design components as well as clarity of the show concept need improvement. These two studies demonstrate the acceptability of the potential effectiveness of a PA-themed reality show concept for conveying active transportation-related messages to viewers. Both studies showed that a PA-themed reality show concept positively influenced PA behavioral intentions specific to AT among those who watched it and impressions of the show as a correlate to behavioral intentions, thus confirming that innovative reality programming can be used to entertain viewers and potentially inspire positive health behaviors.

This dissertation investigates how four half hour viewings of an authentic German television serial over the course of one fourth semester intermediate course in German affect foreign language (FL) students' perceptions about German culture. In recent years, filmic media have become popular learning instruments. However, how they affect the attitudes of the FL learner about the lifestyles, behaviors, and characteristics of that FL culture has remained largely unexplored. This study triangulates questionnaires, classroom protocols, and assessment of student essays to see in what ways students' discuss and write about cultural differences and similarities at the onset of viewing and after the final viewing of a German video serial. Additionally, it investigates whether English or German language class discussions following student viewing of the program are more effective in fostering critical thinking about a foreign culture. Participants in this study were 69 students (24 female and 45 male) enrolled in four fourth-semester classes of the lower-division curriculum of the Germanic Studies Department at the University of Texas at Austin. After reading biographies and related information about characters, all four classes watched four episodes of the popular German television program, Lindenstrabe, without subtitles. While all classes viewed and wrote about the television serial in German, two classes conducted post-viewing discussion activities in German and the other two classes in English. The investigator visited and took notes on all classes and provided instructors with guidelines to enable consistent approaches to relevant materials and assignments. The resulting data were analyzed using statistical (pre- and post-questionnaires) and qualitative analyses (student response papers and classroom protocols). Two central findings were identified: 1) Fourth-semester German students increased their ability to identify and critically discuss cultural issues and their related social implications when exposed to repeated viewings of the television serial Lindenstrabe and when reacting to the program and its content orally and in writing during in- and out-of-class assignments; 2) Students' gender and the language of the classroom discussions influenced the content and analytical style of students' on their essay analyses of the video. These and other findings are assessed in light of classroom variables, in conjunction with suggestions for future research, and implications of these findings for media use in FL classrooms. / text
